這篇文章主要介紹了Smarty中常用變量操作符,實(shí)例匯總了常見的各種變量操作符,非常具有實(shí)用價(jià)值,需要的朋友可以參考下
本文匯總了Smarty中常用變量操作符，分享給大家供大家參考。具體如下：
php模板引擎smarty的變量操作符可用于操作變量,自定義函數(shù)和字符。
語法中使用"|"應(yīng)用變量操作符，多個(gè)參數(shù)用":"??指簟?/DIV>
capitalize[首字母大寫]
count_characters[計(jì)算字符數(shù)]
cat[連接字符串]
count_paragraphs[計(jì)算段落數(shù)]
count_sentences[計(jì)算句數(shù)]
count_words[計(jì)算詞數(shù)]
date_format[時(shí)間格式]
default[默認(rèn)]
escape[轉(zhuǎn)碼]
indent[縮進(jìn)]
lower[小寫 ]
nl2br[換行符替換成<br />]
